Victorian London was notorious for its pickpockets. But in the country houses of the elite, gentleman burglars, art thieves and con men preyed on the rich and titled. Wealthy victims—with their pride and reputation at stake—would never go to the police. What they needed was a society insider, one of their own, a person of discretion and finely tuned powers of observation, adept at navigating intrigue.
That person was Lady Mary Montagu Douglas Scott, the youngest child of Queen Victoria’s close friends the Duke and Duchess of Buccleuch. Bookish, fiercely intelligent, and a keen observer, Mary has deliberately cultivated a mousey persona that allows her to remain overlooked and significantly underestimated by all. It’s the perfect cover for a sleuth, a role she stumbles into when trying to assist a close friend during a house party hosted by her parents at their stately Scottish home, Drumlanrig Castle.
It is at this party where Lady Mary also meets Colonel Walter Trefusis, a distinguished and extremely handsome war veteran. Tortured by memories of combat, Walter, like Mary, lives a double life, with a desk job in Whitehall providing a front for his role in the British Intelligence Service. The two form an unlikely alliance to solve a series of audacious crimes—and indulge in a highly charged on-off romance.
